To ail whom'z't-wwy concern."

' Be it known that I,- NIGHOLAS"LEE MON- sumar, a citizen of the United States, residing at St.-Louis, Missouri, have invented a certain new and useful -Im rovement in Valves, of which the flollofwing is a full clear, and exact (lescri tion, such as will'en able others skilled in t cart-to which it ap pertains to inakeand use the same, reference being had to t'he acoompany-ing drawings, forming part of this specification.

The present invention has relation to improvements in valves and consists of the novel features of construction more fully set forth in the specification and pointed out in the claims. 7

The ob'ect of the invention is to construct a valve t at will at all times firmly seat in the valve seat irrespective of particles of carbondeposit that might be on said seat.

It is well understood that with a valve of ordinary construction, small particles of carbon projecting from the valve seat wilLprevent the valve from contacting" with the seat at all points. v

1 have overcome this objection by providace of a yielding material which, as t eyvalve seats, will compress on the valve seat, thus yielding to any particles of carbon on the seat and bearing on said seat throughout its entire surface.

Further objects will be better apparent from a detailed description of the invention inconnection with the accompanying drawin s, in which,-

igure 1 is a half 10 itudinal section through the valve, and hail elevation.

Figure 2 is a top plan of the valve with parts broken away Referring to t edr'a'wings, 1 represents the valve body, 2 the stem thereof, said stem terminating in a boss 3, provided with flattened sides for the application ofa wrench.

0n the side op osite the b0 3 the valve with a neck4 from which bod is provide y A nut 6 propro ects a threaded stem 5.

vided with a flange 7 is ada ted to screw, onto the threaded stem 5, an a washer or, gasket 8 is adapted to encircle the neck 4..

and be interposed between the'valve body and the, nut 6. The valve body 1 is provided with a beveled edge a and the outer edge of the gasket projects slightly beyond the edge a-and forms, when compressed, a continuation of the beveled edge a. The beveled edge a and the gasket 8 together constitute the valve surface which is adapted to rest in the-ivalve seat, although the gasket 8 only will contact with the valve seat under nor mal conditions. The nut-6 is also provided with a boss 9, having flattened sides for the reception of a wrench; The gasket 8 consists of a'material 'orcomposition that is sulficiently yielding to enable said asket to give, on coming in'contact with a ocalized deposit of carbon, in the seating operation of the valve. The compressible or yielding gasket 8 virtually forms a seal between the valve and the valve seat, thereby causin the vale to seat erfectly, irrespective o the irre 'larit o the surface of the valve seat.

Th: gas et 8, in addition to being compressible, must also possess fire-resisting gualities by virtue of the heat generated uring the operation of the engine, and my invention contemplates the use of any composition which is both'yielding or compressible and fire-resisting or non-combustible. Such a composition, for instance, may be made of asbestos and aphite.

In addition to the 'a vantages obtained by i the compressible qualities 0 which results in a wiping action on the seat. This continuous wiping action during 0 eration of the engine .kee s the seat ohshed and avoids the accuinu ation of car on dethe gasket, I have found that each seating of the valve .casing' produces a squirming of the gasketormed with a beveled surface, and

erably stamped outof sheet material in flat washer form) and saidcap-nut is screwed home, will firmly clamp the flat portion of said gasketdn position and at the same time deflect the marginal edge thereof to pro-' duce a flaring flange which is dis osed at or nearly right angles to the bevele valve seat {snot shown). he edge of the overhangin an'ge 7.forms a guide by which the edge 0? gasket 8- may be dressed or ground to its,

seat.

Having described my invention, what I claim is: v

1. A valve body formed with a beveled surface, a cap-nut formed with a conversely beveled overhanging surface, and a gasket interposed between said body and cap-nut, the marginal edge of said asket being deflected by said beveled sur aces so as to be adapted'to be presented to a valve seat at substantially a right angle.

2. The combination of a valve body element having a beveled surface, and a capnut element having a conversely beveled surface, said elements having threaded engagement, and a gasket clamped between said elements and the edge of which is deflected by said beveled surfaces.

3. The combination of a valve body element having a beveled surface, a cap-nut element havlng a conversely beveled surface, and a gasket of'compressible incombustibl'e material clam ed between said elements, the

edge of whic gasket is deflected by said beveled surfaces and extends slightly beyond the ed e of the beveled surface of the valve body e ement.

4. A valve for an internal combustion engine, the seat engaging portion of which consists in part of the edge of a sheet of compressible incombustible material which sheet is adapted to be presented perpendicularly to the valve seat.

5. In a valve for an internal combustion engine, a seat engaging disk provided with a zone of compressible incombus tible mate rial extending slightly beyond the seat engaging portion of said disk said material being held firmly up to the extreme edge of the disk.

In testimony whereof I hereunto ailix my signature this 30th da of June, 1920.

Certificate of Correction.

It is hereby certified that Letters Patent No. 1,409,393, granted March 14, 1922, upon the application of Nioholea' Lee Monse 'rat, of St. Louis, Missouri, for an improvement in "Va-Ives, were erroueoualy issued to Henry W. Kuechenmeister, es essiguee of the entire interest in eeid intention, whereas eeid Letters Patent should have been issued to the ifwmtor, ed'id Manson- Q d Henry W. Kuechm meiater, jointly, said Kueehemneister Beiug essignee ox one-half interest only in skid invention, as shown by the recofds' of assighments in this ofiice; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent Office.
